RE: HELP CRYSTAL/ORACLE FIGHTING APPROACH CUT DOWN REPORTS
Title: RE: HELP CRYSTAL/ORACLE FIGHTING APPROACH CUT DOWN REPORTS Need bind variables, can't fix them yes will go with global temporary tables but understand that this is going to place I/O on system that may not be necessary. -Original Message-From: Lord, David - CSG [mailto:[EMAIL PROTECTED]]Sent: Tuesday, August 13, 2002 11:03 AMTo: Multiple recipients of list ORACLE-LSubject: RE: HELP CRYSTAL/ORACLE FIGHTING APPROACH CUT DOWN REPORTS Paula I don't know Crystal reports so I'm not sure what you are trying to achieve, but... 1) If you're using 8i and can fix the number of bind variables (or don't need to use them at all) then native dynamic sql (NDS) is faster and easier to code than DBMS_SQL. 2) In either, I don't know of any restrictions on the type of sql you can use. 3) If you're using 8i and want to do the thing with the table, consider using global temporary tables. They look like normal tables but the data is stored in the user's sort area (or thereabouts) so you don't need the session_id. Each session only sees the data it has inserted.

There are lots of different types of queries and he would like to cut-down on the number of Crystal Reports he would need. He wishes to create a table with session i.d. as primary key that will be used to insert aggregate records (rolling averages, etc.) so that he doesn't have to do this. I am concerned about even just 12 concurrent users (maybe?), 67 rows, primary key and index inserts and deletes are unnecessarily incurring I/O. I am suggesting using DBMS_SQL but don't know if there are limitations to the type of SQL you can write - we have inline views/hints/etc.? I just think it would be a more efficient way to do the same thing. He is saying he has been burned before by code generators. I am trying to say that this is a supplied package and not really a code generator and in my experience quite flexible. Help Am I making too much of this? What about metadata tables? In otherwords, keep report name, columns involved or even store query and view name then query actually based on the metadata.

Title: RE: HELP CRYSTAL/ORACLE FIGHTING APPROACH CUT DOWN REPORTS Yes, it looks like NDS may be able to be used - Reading Johnathon Lewis' Practical 8i with refcursor. I think this is a better approach then global temporary table. I will see if there are limitations to this using Crystal. -Original Message-From: Lord, David - CSG [mailto:[EMAIL PROTECTED]]Sent: Tuesday, August 13, 2002 11:03 AMTo: Multiple recipients of list ORACLE-LSubject: RE: HELP CRYSTAL/ORACLE FIGHTING APPROACH CUT DOWN REPORTS Paula I don't know Crystal reports so I'm not sure what you are trying to achieve, but... 1) If you're using 8i and can fix the number of bind variables (or don't need to use them at all) then native dynamic sql (NDS) is faster and easier to code than DBMS_SQL. 2) In either, I don't know of any restrictions on the type of sql you can use. 3) If you're using 8i and want to do the thing with the table, consider using global temporary tables.
